Requirements Management Interface

Opening an Object in the Navigator

You can use the current model or the file for another object. The object's file must be on the MATLAB path or in the current directory.

If the Simulink or Stateflow object you want to associate requirements with is already open and is the currently active model, Select Open Current Model from the File menu in the Navigator.

Note    The top level system of the Simulink or Stateflow model must be active. For example, if the Simulink f14 model is open with the controller subsystem active, then Open Current Model will not work in the Navigator.

If the Simulink or Stateflow object you want to associate requirements with is not currently open, or if you want to associate requirements with a MATLAB M-file:

1. Select Open File From the File menu in the Navigator.

1. The Open Model/File dialog box appears.

2. Select the object that you want to associate with requirements and click Open.

1. The object opens in Simulink or Stateflow.

Note    While using the Navigator, do not close the model in Simulink. In addition, if you close DOORS while using the Navigator, MATLAB closes. If the object has changed, MATLAB prompts you to save your changes.

For a Simulink or Stateflow object, the subsystems, blocks, charts, states, and transitions appear as nodes in a hierarchical tree structure in the left pane of the Navigator. An M-file appears as a single node in the left pane of the Navigator.

Simulink Model in the Navigator

This example shows the Simulink engine model in the Navigator.

Stateflow Chart in the Navigator

This example shows a partial view of the fuelsys model, which contains the control logic Stateflow chart in the fuel rate controller subsystem.

You must have Stateflow installed in order to expand the Stateflow chart node in the Navigator.

MATLAB M-File in Navigator

This example shows a MATLAB M-file, engine.m, in the Navigator.
